Consider the equation $y=-x^2$y=−x2
Complete the following table of values.
$x$x | $-3$−3 | $-2$−2 | $-1$−1 | $0$0 | $1$1 | $2$2 | $3$3 |
$y$y | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |
Plot the points in the table of values.
Hence plot the curve.
Are the $y$y values ever positive?
No
Yes
What is the maximum $y$y value?
Write down the equation of the axis of symmetry.
Consider the quadratic $y=3x^2$y=3x2.
Consider the quadratic equation $y=-2x^2$y=−2x2.
